Abstract
An anti-noise system for influencing exhaust noises propagating through a multi-flow exhaust system includes a controllerand at least one actuator. The at least one actuator is disposed in a sound generator, connected to the controllerfor receiving control signals, and adapted to generate sound inside the sound generator. The sound generatoris connectable to at least two exhaust tractsof the multi-flow exhaust system of the vehicle simultaneously. The controlleris configured to generate a control signal that prompts the at least one actuator disposed in the sound generatorto cancel sound inside the at least two exhaust tractsof the vehicle's multi-flow exhaust system at least in part and preferably completely.
